A 27-year veteran of the Chicago Police Department and twice-shortlisted Police Superintendent, Police Accountability Task Force member Hiram Grau also worked in the Cook County State’s Attorney’s Office and as Director of the Illinois State Police.

Grau, originally a native of Puerto Rico, spent most of his childhood at Grand and Ogden avenues in the Patch neighborhood of Chicago with two siblings. He graduated from Holy Trinity High School in 1967, and was drafted to serve for 13 months in the U.S. Army’s 101st Airborne Division in Vietnam, where he served with distinction, earning four medals.

He joined the Chicago Police Department in 1981 and worked his way up from Patrolman to Tactical Officer, Gang Crime Specialist, Detective, Undercover Narcotics Officer, Sergeant, Lieutenant, Watch Commander, District Commander, Deputy Superintendent, and Acting First Deputy. Much of that time was spent in gang investigation units, including 9 years on the FBI's Street Gang Investigation Squad.

In 2003, Grau became deputy superintendent of the Bureau of Investigative Services, putting him in charge of more than 2,300 officers in the detective and organized-crime divisions. He and then-Superintendent Philip Cline worked with other law enforcement agencies to formulate a plan to take down the worst gang leaders in Chicago, called "Target 21". The plan involved multi-agency cooperation to build cases against the 21 worst gang leaders in the area. In two years, Target 21 led to the arrest of 16 high-ranking gang leaders.

Grau’s departmental purview at Investigative Services included the 2004 Koschman case. He was twice considered to become Police Superintendent, making it to the top 10 in 2003 to replace Terry Hillard, and to the top three in 2007 to replace Phil Cline.

While at CPD, Grau received his B.A. in Criminal/Social Justice in 1996, and his MBA from Saint Xavier University in 2003.

After retiring from the CPD in 2008, Cook County State’s Attorney Anita Alvarez asked Grau to work as second in command in the Investigations Bureau, where he oversaw the Narcotics/Special and Municipal Investigations Divisions. In 2011, Gov. Pat Quinn asked Grau to replace Jonathon Monken as head of the Illinois State Police. He was approved unanimously, and was the first Latino to head up the force.

Grau was credited with meeting every statutory deadline during the implementation of Illinois’ concealed carry program, authorizing the use of tasers by troopers, and renewing the ISP’s efforts on diversity and recruitment, and also oversaw state troopers during the 2012 NATO Summit. In 2011, when the State's Attorney Anita Alvarez requested ISP take over the Koschman investigation before Grau’s nomination, Grau wrote to Gov. Quinn requesting the Department turn down the request because of his time at CPD and with the State's Attorney’s office: “A review of this matter by ISP during a time when I am director would lead to questions, fair or not, about the integrity of the review.”

Grau retired from the Illinois State Police in January 2015, around the same time as Gov. Bruce Rauner’s inauguration. In December 2015, Mayor Rahm Emanuel announced Grau would be one of six-members on the Task Force on Police Accountability formed in the aftermath of the release of the Laquan McDonald video.
